Staffers of a Chelsea club with a history of trouble tried to keep cops from helping three partyers who apparently overdosed yesterday, police said.

Cops received several 911 calls around 9 a.m. from inside Club Twilo on West 27th Street, saying that patrons were passed out inside, according to sources.

Club staffers tried to keep cops out, telling them that everything was all right, but after more calls and nearly an hour of dickering, the officers searched the club over the objections of the bouncers, police said.

They found three patrons lying unconscious inside a closet, cops said.

Sources told The Post that if people pass out in Twilo, “the bouncers drag them into a room until it wears off.”

Other Sunday morning patrons of the club were described by a source as “a bunch of zombies walking around.”

The apparent overdose victims, two men and a woman, were rushed to St. Vincents Hospital. They told cops they had taken a drug called “Liquid G.”

Police arrested one of the bouncers, Joseph Murray, 30, of Queens, on obstruction and reckless endangerment charges.

Two clubbers have died at Twilo of suspected overdoses and the hot spot was raided by police along with 10 other bars in August.

A 19-year-old was slashed across the face outside the club in January.

City officials sued to close Twilo last year, calling the club a “nuisance.”
